I am new to chickens and have a question about separating chicks and keeping one by itself. I have 6 week old Dominickers, 4 week old RIR's, and four 3 week old Americanas. All but the Americanas have been put outside into the coop with a lamp. I would like to add in the Americanas, BUT one of them is a runt. It is literally 1/3 the size of its hatch mates. It only has it's wing feathers coming in, and it just so much smaller. My question is this: Can I put the other three outside in the coop and keep the runt inside in a brooder? Is it okay to separate one chick by itself? From other posts about runts, it sounds like it probably won't make it anyway. OR should I go ahead and put them all in the coop and hope for the best. Will it's hatch mates "protect" it in any way? It doesn't have pasty butt, but it does have a hard lump near it's anus, not the crop. From prior reading, I tried molasses, olive oil, warm water bath soaks, massaging, etc. It is eating, drinking, scratching, behaving normally.
